Description / Abstract:

Definition and purpose

Spring-type straight pins (also known as roll pins) according to this Standard are pins made of spring steel, rolled from strip and having a slot along their length and one or two chamfers to permit insertion. They are mainly used for connecting two or more parts of an assembly and are suitable for withstanding shear loads. They can also be used for bolted joints where it is desired to avoid relative movement of the bolted parts without applying a high pre-stress. The nominal diameter of spring-type straight pins is also the nominal diameter of the accommodating hole, for which tolerance zone H12 should be used.

Note: With very high loads, it is advisable to use compound spring-type pins. According to the nature of the load and the particular installation conditions, the following combinations can exist:

Heavy type DIN 1481 outside+ heavy type inside

Heavy type DIN 1481 outside+ light-weight type DIN 7346 inside

Light-weight type DIN 7346 outside+ heavy type DIN 1481 inside

Light-weight type DIN 7346 outside+ light-weight type inside
